AI Technical Summary

Benefits of technology

This approach significantly reduces oil content rates to less than 0.01 weight percent, eliminating the need for separate oil recovery apparatuses and enhancing compressor efficiency by effectively separating refrigerant and oil within the compressor.

Problems solved by technology

The lubricant oil mixed with the refrigerant reduces a cooling efficiency and causes a lack of the lubricant oil inside the compressor.
However, the oil content rate from the lower compression type compressor is not negligible, so that it is common to install the separate oil recovery apparatus or oil separator.

Embodiment Construction

[0064]Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

[0065]First, a compressor that may be applied to one embodiment of the present disclosure will be described in detail with reference to FIG. 1.

[0066]FIG. 1 illustrates a cross-section of a scroll compressor that may be applied to one embodiment of the present disclosure. Since a compressing portion is located below a driving motor, the scroll motor may be referred to as a lower compression type compressor or an upstream compressor.

[0067]For convenience of description, upper / lower position may be named based on the compressor, which is vertically located. Further, upstream / downstream position may be named based on flow of refrigerant and a position of the driving motor 120. In the same compressor, “upper” means downstream, and “lower” means upstream.

Abstract

A compressor includes a case, a driving motor including a stator mounted inside the case and a rotor disposed radially inward of the stator and rotatable, a centrifugation space defined inside the case by one side of the driving motor and the case, a discharge pipe passing through the case and defining a refrigerant inlet hole, a rotation shaft coupled to the rotor to rotate, a compressing portion defined at the other side of the driving motor, where refrigerant is compressed by rotation of the rotation shaft, and a rotating member disposed to spread a rotary power of the rotor to the centrifugation space, thereby providing a centrifugal force to refrigerant and oil. The rotating member is disposed at one side of the rotor to rotate integrally with the rotor.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application Nos. 10-2018-0138497, filed on Nov. 12, 2018 and 10-2018-0138499, filed on Nov. 12, 2018, which are hereby incorporated by reference as if fully set forth herein.BACKGROUNDField[0002]The present disclosure relates to a compressor, and more particularly, relates to a compressor that may effectively separate lubricant oil and compressed refrigerant from each other within the compressor.Discussion of the Related Art[0003]In general, a compressor is applied to a refrigerant compression-type refrigeration cycle (hereinafter, referred to as a refrigeration cycle) such as a refrigerator or an air conditioner.[0004]The compressor may be classified into a reciprocating compressor and a rotary-type compressor based on a scheme of compressing the refrigerant, and the rotary-type compressor may include a scroll-type compressor.[0005]The scroll compressor may be classified into an upper ...
